How to make a guitar egg shaker
Cello to bass conversion. Naively thought I was onto something newish but of course found useful info on utube and a website belonging to a creative muso named Dennis Havlena. First option I will try is, this is for a 1/2 cello, modifying nut/bridge/tailpiece to accept Fender light guage flatwounds for electric bass, all recommended by Dennis and easier than option two, my first idea, which was to fit the compound rubber type 'micro-bass' strings. There are utube vids of both ideas and In either case the volume of the body is twice or more that of the 5/16 classical micro-bass so I expect better acoustic volume, especially with the fat strings. Bit of fun, still expect to electrify and plug in.
Thanks, I ended up moving the bridge so the scale(nut to saddle) was 21 inches and converted it to fretless. All is well and happy with the result. AQUILLA nylagut strings work the best. I have tried other and they break, especially the D and G strings.So what are you building? What is a cello/bass. Will you bow it or pluck it, regarding extending the strings, maybe you could extend the tailpiece. Still anchor it over the end edge but extend it somehow to meet the strings, part way towards the bridge etc??
New to this forum, don't know if anyone else replied but the scale length seems spot on to me if I'm right in thinking that the 27/79" refers to the total length of string needed for that instrument with the scale mentioned that should be ok as the strings come long enough unless that small guitar has a tailpiece at the bottom end which could need longer strings than if they just went to a glued-on-top bridge. I have just measured some new strings I have received (D'Addario NYLTECH EJ88UB for ubasses) and their total supplied length is just over 805mm/31" so that could do. My cello-micro-bass project will use the same strings but with the very high bridge and tailpiece I will have to develop a method to add wire tails to the strings to lengthen. Hopefully a lightbulb moment will occur as there are a few design challenges.
I have successfully made one of these 'micro-basses' with this type of strings (of which there are now several brands) using a new, cheaply bought 5/16 classical guitar as the donor instrument. My searching found that this instrument size was perfect for the strings recommended scale length, in this case the scale is 550mm or just under 22". The wider classical neck is perfect for the fat strings, the original tuners I even used by carefully drilling out the barrels. Undersaddle pickup and pre-amp equalizer all sourced cheaply online means the entire project including donor instrument (new) was $133.00 New Zealand. So much fun to play. Been using it through large and small amps with huge satisfaction for over a year. Next project is the same idea, cheap online cello, 1/2 size is ideal for correct scale length, modified to be a micro-double-bass. The width of the neck at the nut will need some attention perhaps but this will yield a fretless bass with crowned fingerboard, lovely body and all up about double the cost (hope to keep it under 300.00 NZ) of the classical instrument hack. There is a fine instrument/maker luthier here in New Zealand who scratch makes a similar thing out of beautiful woods, calls it a 1/4 bass and it sells for about 2000 NZ dollars. If it fails to please I will reconvert to cello and sell it off, or will I? small house, many instruments, Ha!
Hi, I am thinking about doing this with a small kids electric guitar. I have a few questions.Would the Ubass strings fit into the bridge of a bass guitar?Would the Ubass strings even work with an electric guitar? I imagine hey do since there are many electric UbassesIs there anything else I should be careful of?THANKS!
I have a small guitar with a aprox. 22.5 inch scale length. I am considering converting it to a UBass type instrument. Would Aquila thundergut or Ashbory strings stretch sufficiently for this length which would range from 27 to 29 inches?
Hi! I was looking for something like this! I was wondering whether it would sound louder with a 3/4 steel guitar!I'd like to try and make it soon!
